Causes of narcissistic personality disorder (NPD)

2-minute read

As with many personality disorders, the exact cause of narcissistic personality disorder (NPD) is unknown. It is probably a mixture of genes, early childhood experiences and psychological factors.

Early childhood risk factors include:

  • insensitive parenting
  • over-praising and excessive pampering - when parents focus intensely on a particular talent or the physical appearance of their child as a result of their own self-esteem issues
  • unpredictable or negligent care
  • excessive criticism
  • abuse
  • trauma
  • extremely high expectations

Other possible factors include:

  • abnormalities in the genes that affect the connection between the brain and behaviour
  • being over-sensitive

Although there is no one answer to the question of what causes NPD, professionals agree that the sooner treatment begins, the better a person's chance for an improved quality of life.
